For the do-it-yourselfer, CURT offers an entire line of towing fabrication components to supply you with the quality building blocks you need. These raw steel components are made from solid steel for maximum strength, and they come ready to be welded together in whatever form you need to get the job done. CURT fabrication steel receiver tubing can be used to extend the reach of your receiver or to create a piece of custom towing equipment. Each unit is equipped with a 1/2" reinforcing collar for extra strength and has a raw finish to be ready for welding. This receiver tube has a 2" x 2" opening and measures 12" in length.
